FREQUENCY DENSITY OF A CLASS INTERVAL

Frequency density of a class interval may be defined as the ratio of the frequency of that class interval to the corresponding class length.

To have better understanding on frequency density of a class interval, let us consider the frequency distribution given below.

The frequency densities for the first two class intervals of the frequency distribution of weights of 36 students are

3/5 and 4/5

That is, 0.60 and 0.80 respectively.

Apart from "Frequency density of a class interval", let us look at some other important terms associated with a frequency distribution.
